Accepted name: mycodextranase

Reaction: Endohydrolysis of (1→4)-α-D-glucosidic linkages in α-D-glucans containing both (1→3)- and (1→4)-bonds

Other name(s): 1,3-1,4-α-D-glucan 4-glucanohydrolase

Systematic name: (1→3)-(1→4)-α-D-glucan 4-glucanohydrolase

Comments: Products are nigerose and 4-α-D-nigerosylglucose. No hydrolysis of α-D-glucans containing only 1,3- or 1,4-bonds.
